IMPROVEMENT 1N sAw-HANDLES.

Specification forming part of Letters Patent hlm-173,600, dated February 15, 1876; application filed Y January 2l, 1875.

vTo all whom it may concern:

. secure the handle to the blade.

In the accoinpanyingdrawing, Figure 1 is a side view of my improved handsaw Fig. 2, a view of the blade with the handle removed;

and Fig. 3, a section on the line, 1 2, Fig. 1.

A large portion ot' the plate from which the blade ot' a handsawl is cut has to be discarded, owing to its imperfection; for instance, a: represent the ragged end of the plate,which, in forming an ordinary saw-blade, must be cut oft' to about the dotted line y y, for that' portion of the .plate is usually oi' such inequality as regards thickness that it cannot be incorporated in a finished blade. Instead of discarding this part of the plate, I utilize it as a means ot' securing a cheapl and simple handle to the blade, as shown in the drawing.

I form in the blade an opening, d, -of a proper shape for receiving the operators 1ingers, and at the rear ot' this opening is the segmental portion, b, which is formed of that portion ot' the plate which is commonly cut o and sent to thev scrap heap. Y

The handle, instead of embracing' a large portion of the butt of the blade,as usual, oo nsists simply of thev grip h, having two projections, v, and i', and this handle is slotted for the4 reception of the segmental portion b of the blade, the inner edge of the handley coinciding with the edge of the opening d. Two bolts only are required'for securing the handle to the blade, one bolt passing through each of the projections i audhi.

In -order that the fingers of the operator may not bev wounded by theA comparatively sharp edge f of the opening in the blade, I tit to the latter a slotted wire, w, (shown in section in Fig. 3,) the wire being bent to conform to the edge of the opening, and Vone end` of the wire being embedded in the projection i of the handle, and the other in the projection 'i'. l

The advantage'ot1 this invention is, that but little wood is used in the construction ot' the handle -compared with that demanded in making anlordinary handle, and fewer bolts than usual are required to' secure the handle to the blade.

I do not claim strengthening the handle by continuing the blade into the same, nor do I claim, broadly,reeessng the butt ofthe blade but l I claim as my invention- The combination of the handle, having a gripe, h, and two projections, arranged as described, and a slotted wire, w, adapted to the edge of the opening in the blade and to recessesin the handle, all as set forth.

In testimony whereof I have signed my name to this specification in. the presence of two subscribing witnesses.

HENRY DISSTON.
